US fuel gauge exposure fell by more than half in three months
Overview
Recent research shows that the number of U.S. internet addresses responding to queries from fuel tank gauge protocols has dropped significantly. In June, only 2,354 addresses were detected, a steep decline from the usual 4,800 observed monthly for nearly a year. This reduction occurred over three months—April, May, and June—and is notable as it falls below previous annual lows. The findings suggest a rapid decrease in exposure, which is uncommon in this field. This decline is important because it may indicate improved security measures or changes in how these systems are monitored or accessed, potentially reducing the risk of unauthorized access or cyberattacks on fuel management systems.

Original Article Summary
Every month for the better part of a year, about 4,800 US internet addresses answered a query in the protocol that fuel tank gauges speak. In June the number was 2,354. The count fell across April, May, and June, all three months sit below the previous year’s floor, and the decline holds up against checks for address churn and port hopping. Exposure figures rarely move this way, and almost never this fast.
